RAIL-JOINT.

Speciication of Letters Patent.

Patented Nov. 30, 1909.

Application led January 8, 1909. Serial No. 471,261.

To all whom it may concern:

Be it known that I, MoNs THoRsoN, a subject of the King of Norway,residing at Sanders, county of Rosebud, and State of Montana, haveinvented certain new and useful Improvements `in Rail-Joints, of whichthe following is a specification.

My invention relates to improvements in rail joints, the object being toprovide a more substantial construction in a rail joint than hasheretofore been employed in this class of work.

A further object of my invention is to provide such a construction in arail joint that the pounding and vibration incident to the ordinaryconstruction will be overcome.

A further object of my invention is to provide fish-plate interlockingmeans to prevent relative longitudinal movement of the same. And afurther object of my invention is to make special provision formaintaining the contiguous ends of the rails in alinement.

Other objects will appear hereinafter.

With these objects in view, my invention consists in such a novelconstruction and arrangements of parts all as will be hereinafter fullydescribed and particularly pointed out in the appended claim.

My invention will be more readily understood by reference to drawingsforming a part of this specification and in which,

Figure l is a side elevation showin my improved rail joint in itspreferred form Fig. 2 is a plan view partly in horizontal section, Fig.3 is a detail side elevation showing the inclined surface of one railwhich is adapted to come in contact with a similar inclined surface ofthe other, Fig. 4 is a detail longitudinal section showing theiish-plate construction, Fig. 5 is a transverse section taken on theline 1eof Fig. 2, Fig. 6 is an end elevation of a rail, and Fig. 7 isatransverse section taken on the line y-y of Fig. l.

Referring now to the drawings, l indicates the rails and 2 the railjoint fish-plates. The ends of the rails 1 are tapering as shown, theinclined surfaces 3 being adapted to come in contact with each otherwhen the joint is made. This obliquely disposed joint is much theaccompanyingl preferable to the ordinary joint having square rail ends,since the usual vibration caused by car wheels coming in contact withthe joint is overcome. It is obvious that whatever the contraction orexpansion of the rails the tread of the rails is always continuous anduniform. The lish-plates 2 are provided with a channel portion 4 adaptedto conform to and engage the foot of the rail, and a vertical portion 5adapted to engage the web Aor vertical portion of the rail. A series ofteeth 6 are provided in each fish-plate 2, said teeth being adapted tomesh to prevent relative movement of the fish-plates. The reducedextension 7 in the rail l is made straight and formed with bevel edges 8adapted to fit snugly between the head and foot portions of the rail,thus forming a rigid construction. The bolt-holes in the fishplates 2and rails l register, and the rail bolts 9 when secured in positioncomplete the rail joint.

While I have shown what I deem to be the preferable form of my device, Ido not wish to be limited thereto as there might be many changes made inthe details of construction and arrangements of parts without departingfrom the spirit of my invention.

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

In a rail joint, two rails having overlap ping beveled ends providedwith integral reduced extensions having beveled edges adapted to contactwith the head and foot portions of the opposed rail section; fish platesadapt ed to engage the rail ends and having flanges extendinghorizontally to meet under the rail, the said flanges being providedwith alternate intermeshing teeth and notches `on their meeting edges;and bolts passing through said fish plates and rail ends, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MONS THORSON.
